Abstract
Perfeccionamientos en aparatos hidráulicos portátiles para curvar tubos controlados a mano, provistos de una cabeza de acoplamiento rotatoria y elementos curvadores reversibles para invertir la dirección de curvatura de un tubo, caracterizados porque cada aparato se forma por un cuerpo de aparato cuyo extremo sostiene una cabeza de acoplamiento rotatoria y forma parte íntegra de un elemento de sustentación compuesto por una placa extendida longitudinalmente hasta el aparato, cuya placa tiene dos espigas paralelas que, a su vez, sostiene el elemento curvador que realiza la función de un elemento curvador fijo, sobresaliendo las espigas de la superficie de la placa de sustentación que es la superficie deslizante del elemento curvador móvil, cuyo elemento curvador móvil se conecta al extremo libre del vástago de un pistón del aparato y se mueve con el mismo, por consiguiente, cuando es accionado por el operario actuando repetidamente la palanca, teniendo los elementos curvadores fijos y móvilla posibilidad de colocarse de una forma reversible sobre las espigas que sobresalen de la placa o en el extremo del vástago del pistón, respectivamente, de acuerdo con la dirección de curvatura deseada de un tubo.
